Draft Design for a Complex Machine to Generate Electricity from Water Power

Alexander is designing a “complex machine” for his 8th grade science class. He recorded a short AudioBoo today and described his design, which I photographed and embedded below. Please share comments and feedback.

Complex Machine Design

I shared the “Sweeping Down the Plains” STEM project from K20-ALT with him this week for ideas and inspiration. See Video Part 2 on the project page, starting at the 4:46 point to see the design for an electrical generator/dynamo using a wind generator design. The Google Doc lesson plan includes the supplies used for their project. This extremely clever design uses a CD, neodymium magnets from AmazingMagnets.com, a wooden skewer like those used on a BBQ grill, a suction cup, and other inexpensive items. Hat tip to Adam Zodrow for sharing this amazing project with me a few weeks ago. See this post and podcast on Oklahoma EDUshare for more info about this project and K20-ALT.

I’m thinking Alex’s greatest challenge will be building the water wheel, gears, and the dynamo. This is going to be a great opportunity for problem solving, engineering, design and tinkering!
